The concept of BVA is to figure out whether the observed broadness of FRET distributions are owing to the molecular dynamics, by comparison of a calculated standard deviation ($s_E$) of FRET efficiencies for sub-bursts ,comprised of \textit{n} consecutive photons within the burst, from a mean FRET efficiency for a burst to an expected standard deviation based on shot noise limited distribution~\cite{Torella_2011}.   If the observed broadness originates from different molecules having distinct FRET efficiencies without dynamics, $s_E$ of each burst is only affected by shot noise and will follow the expected standard deviation curve rationalized by a binomial distribution (see equation 4 in~\cite{Torella_2011}). However, if the observed broadness is due to dynamics of single species of biomolecules, $s_E$ of each burst has is expected  to be larger than the expected standard deviation and sits on above the expected standard deviation curve as shown in figure .
